BENCH-VISE.

SPECIFICATION forming part of Letters Patent No. 641,457, dated January16, 1900.

Application fil d, October 16, 1899. Serial No. 733,747. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. LIGHT, a citizen of the United States,residing at Lebanon, in the county of Lebanon and State of Pennsylvania,have invented certain new and useful Improvements in Bench-Vises; and

V I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. i

My invention relates to vises, has especial reference to that class ofvises known to the trade as bench vises, designed to be secured to thetop of work-benches, and has for its obj ect a simple constructionwhereby the vise can be readily adjusted to different angles and rotatedaxially for the convenience of the workman; and it consistsin certainimprovements in construction, which will be fully disclosed in thefollowing specification and claim. In the accompanying drawings, whichform part of this specification, Figure 1 represents a side elevation ofmy invention; Fig. 2, a top plan view of the same; Fig. 3, a sideelevation, partly in section, of the outer jaw; Fig. 4, a transversesection of the body of the vise; Fig. 5, a top plan view of the same;Fig. 6, a top plan view of the inner jaw; Fig. 7, a side elevation,partly in section, of the same; Fig. 8, a front end view of the same;Fig. 9, a transverse section of one of the adj ustable cheeksface-pieces, and Fig. 10 a vertical longitudinal section of the same.

Reference being had to the drawings and the letters thereon, A indicatesthe body of the vise,cylind rical in form and separated longitudinallyat a, the two parts of the body being contractible andexpansible toclamp the shank of the inner jaw in any position of adjustment onitsaxis, and is provided with lugs 79 I), having screw-threaded holes 0 cand a screw-threaded adj usting-bolt d. The body is also provided with acircular flange e and a circular projection f, which respectively restsupon the circular base B and enters the opening 9 in the base. The baseis provided with a series of apertures h, arranged in a circle, whichare engaged by pins 1' 2', supported in apertures 1s 7c in the flangese, which apertures register with the apertures h in the base B and bywhich the body of the vise is secured in any desired position of rotaryadjustment.

The base is provided with lugs Z, by which the vise is permanentlysecured to the top of a work-bench by suitable screws or bolts, (notshown,) and the body A is secured to the base B by a disk 'm, whichengages a recess or seat a in the lower side of the base and is securedto the projection f by screws 0 to allow the body A to rotate on thebase.

The inner jaw O is provided with a cylindrical shank p, which engagesthe cylindrical passage or bore q of the body A to rotate thereon, andthe shank p is provided with a passage r, non-cylindrical and preferablyrectangular in cross-section to prevent rotation of the jawD and itsshank 8 within the shank p, and in the passage 1" is a fixed nut t, withwhich the screw E engages to adjust the outer jaw D with reference tothe inner jaw O to secure articles between the jaws. The shank s of theouter jaw D is non-cylindrical and preferably rectangular incross-section and fits and slides in the rectangular passage r of theshank p as it is moved in and out by revolving the adjusting-screw Ethrough the medium of the bar a, which engages the head 0, secured tothe outer end of the screw.

The jaws O and D have concave or semicircular faces to and are providedwith cheeks or face-pieces to, which are convex or semicircular on theirinner sides and are secured tothe jaws by a dovetailed connection y toslide thereon for adjustment to different angles of inclination tosecure articles of varied configurations between the adjustment-faces ofthe cheeks.

The vise may be adjusted to any angle desired throughout a completecircle by turning the shank p in the bore g of the bodyA and is thensecured by contracting the body by means of the screw-bolt d, and thebody of the vise may be rotated to any desired de-' gree throughout acomplete circle by removing the pins it and then securing the body onthe base by returning the pins to their normal position in the aperturesh.

It will be observed that the apertures h in the base B are alwayscovered by the flange e, except when the apertures are passing over themin the rotation of the body A, and thus prevent any foreign matterfalling in the apertures.

Having thus fully described my invent-ion, what I claim is I A visehaving an expansible and contractible body and provided with a circularflange, a projection below said flange, a base having an opening engagedby said projection and a seat below said opening, a disk engaging saidseat and means for rotatably connecting said body to said base; incombination with suitable apertures in said flange, apertures in saidbase arranged in a circle, pins for securin g the two parts againstrotation, a jaw having a cylindrical shank and a non-cylindrical passagetherethrough, a jaw having a non-cylindrioal shank engaging the passagein the former shank, and an adjusting-screw.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM H. LIGHT.
